Application filed November l0, 1884. (Model.)

To will whom t may concern.-

Be it known that I, DANIEL OHARA, of Walthalmin the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Watch-Cases, of which the following is a full, clear, and exact description? This invention relates to the construction of the various parts of a Watch-case for their attachment to each other to secure the inclosure of the Watch-movement, and under the invention, first, the band or ring to contain a watchmovement, arranged therein in the usual Way or in any other suitable manner, is made with a bevel or taper at and across its exterior face or edge, and the central .shell or body or annulus to surround and hold said movementring is made with a bevel or taper at and.l across its interior face or edge corresponding to the exterior taper of the ring, all in manner and forni, with the ring placed and forced into the central shell to secure a jointing of the two sufficiently tight and close to attach the one to the other, and to prevent the entrance of dust and dirt and moisture at such joint; second, the central shell or movementring, or both, are made with either an exterior or an interior, or both an exterior and an interior, bevel or taper, and the other parts necessary to complete the inclosure of the movement in the n1ovement-ring-such, for instance, as a front or a back bezel-ring or a front or back cap, cover, or plateare made with a corresponding bevel or taper to suit the bevel or taper of the part of the annulus to which theyl belong, all in manner and form, With such parts placed in position and forced upon their proper parts of the central shell or movement-ring, as the case may be, to secure a jointing thereof sufficiently tight and close to attach them thereto, and to prevent the entrance of dust and dirt and moisture at such joints; third, the movement-ring is made with a bevel or taper at and across its exterior face or edge, and the central shell or body is made with a bevel or taper across its interior face or edge corresponding to the exterior taper of the ring, and otherwise made with a taper or bevel exteriorly or interiorly, or both, for receiving the other parts of the case necessary to complete the inclosure of the movementsuch, for instance, as a front or a back bezelring or a front or back cap, cover, or platewhich are correspondingly beveled or tapered,

all in manner and form,with the several parts placed in position and forced upon their proper parts of the central shell, to secure a jointing thereof sufficiently tight and close to attach them thereto, and to prevent thel entrance of dust and dirt and moisture at such joints; 6o fourth, the central shell or movement-ring, or both, are made with either an exterior or an interior, or With both an exterior and an interior, bevel or taper and the other parts necessary to complete the inclosure of the movement in the movement ring-such, for instance, as a front or a back bezel-ring or afront or a back cover or plate-are made with a corresponding bevel or taper to suit the bevel or taper of the part of the central shell or move- 7o ment-ring to which they belong, all in manner and form, with such parts placed in position and forced upon their proper parts of the central shell or movement-ring, as the case may be,to secure a jointing thereof sufficiently tight and close to attach them thereto, and to prevent the entrance of dust and dirt andv moisture at such joints, and, furthermore, made with a ange or rim in position to lap over the outer edge or periphery of the central shell 8o sufficiently to conceal and close the joint between the parts of the case attached to the central shell or movement-ring, as the case may be; fifth, the winding key pipe or spindle or plug in its length is made of aconical or taper- 8 5 ing shape, and a seat therefor in the central shell is made of a corresponding tapering or conical shape. i

In the accompanying plates of drawings this invention is illustrated on an enlarged 9c scale as carried out in various Ways, allembracing its essential features of the taper and bevel jointing of the parts of the case to inclose the movement.

Figures l to 9, both inclusive, are cross-sec 95 tions, Figs. 1, 2, 3, 4:, and 9 being full, and Figs. 5, 6, 7, and 8 partial, sections. Figs. 10 and 11 are views in detail of this invention, illustrating it as applied to a stand or pedestal for supporting the watchmovement,which rco stand makes one part of the case.

In the drawings, A is the band or ring to contain the Watch-movement. B is the central shell or body or annulus. C, Figs. 2, 4,

7, and 9, is the front bezel-ring, having a crystal, D; and E, Figs. 4. and 7, is the back bezelring, having a crystal, F.

In Figs. 1, 3, 6, and 8 crystals corresponding to the front and back crystals, D and F, carried by the front and back bezel-rings, C

and E, of Figs. V2, 4, 7, and 9, are attached directly to the central shell, B-that is, Withoutthe interposition of bezel-rings-and in Fig. 10 a front crystal is similarly attached.

In Figs. 2 and 9 a back cap or plate or cover, G, is attached in Fig. 9 to the central shell, and in Fig. 2 to the movement-ring A, and this plate in Fig. 10 is carried by a stand or pedestal, H. The movement-ring is made of a bevel or taper, J, at and across its outer face or edge, and the central shell is made of a corresponding bev-el or taper, K, at its interior periphery or `edge in the direction of.

the side N opposite to said side M toward and Y meeting the taper from that side N.

In Figs. 2 and 9 the front bezel-ring, C, is beveled or tapered at and around the inner face of its ilange or rim a, fitting over a corresponding taper or bevel, b, at and aroundv the outer vertical face of a rim or ilange, d, of the central shell in Fig. 9 and of the movement-ring in Fig. 2.

In Figs. 4 and 7 the front bezel-ringwis beveled or tapered at ,and around the outer face of its ange or rim a, tting Within a corresponding taper or bevel at and around the inner periphery of the central shell and wherein the movement-ring is placed.

In Figs. 4 and 7 the back bezel-ring is beveled or tapered at and around the outer face of its flange or rim f, fitting Within a corresponding taper or bevel at and around the inner periphery of the central shell.

In Figs. 2 and 9 the back cap or plate is beveled or tapered at a-nd around the inner face of its flange or rim g, iitting over a corresponding taper or bevel at and around the outer periphery of the central shell, Fig. 9, and of the movement-ring, Fig. 2.

In Figs. 1 and 8 the front and back crystals fit, by their outer beveled or taperededge, within the corresponding bevel or taper at and around the inner periphery of the central shell, and in Fig. 11 the same is true of the front crystal only, the back of the central shell being closed by the raised projection G on the upper face of the stand or support H, which is beveled at and around its edge, fitting within the corresponding bevel or taper at and around the inner periphery of the central shell.

p In Figs. 3 and 6 the front and back crystals iit, by the beveled or tapered inner face oftheir rim or ilange h, over the bevel or taper at and around the outer edge of the central shell.

In Figs. 2 and 7 the parts of the ease covering the front and back sides of the central shell are provided with a iiange or rim, 7c, which laps over the extreme outer edge or periphery of the central shell and conceals and covers up the joint made between such parts and the central shell.

In Fig. 8 the central shell is made in tWo parts, which are correspondingly tapered or beveled, the one part around its outer edge or periphery, and the other part around its inner edge or periphery.

FromA the description given it is to be seen that the `jointing of the several parts making up the case is made bya taper or bevel of the contiguous faces thereof, which in all cases is made to correspond in manner and form to produce a tight and close jointing and attachment of them when they are placed in position upon each other and forced to their seats. By this construction and jointing of the several parts when the parts are properly applied together a most secure and rigLd attachment is obtained, excluding all entrance of dirt, dust, and moisture, which, obviously, if the bearing-surfaces are ground will be increased in some considerable degree. At the same time the parts can be separated with readiness and ease when desired.

Set-screws may be applied to the several partsto rigidly fasten them; but they are not though-t necessary or essential, as the tapering construction of the joints is sufficient for all practical purposes, and more especially so for the purposes for Which the improvements in Watch-cases herein particularly described are to be usedto Wit, for the casing and display of movements in the trade.

L2is the key pipe or spindle or plug, located in the pendent knob M2 of the case. This keypipe L is conical or tapering along a portion of its length, and this portion ts Within a cor` responding conical or tapering socket or tubular bearing, N2, of the pendent knob.

In Figs. 1, 2, 6, and 9 the key-pipe passes through the movement-ring to engage with the movement, as ordinary, and for operation is turned around Within the tapering or conical. bearing N2 therefor of the pendent knob.

In Fig. 4 the key-pipe is incased Within a tapering or conical plug, Owhich ts Within a corresponding conical or tapering bearing of the central shell, B, and when it is to be used it, With said plug, is removed from t-he case, and it is unscrewed from the plug and entered through the conical bearing into the movement through a hole (not shown) in the movement-ring.

The taper of the key-pipe and of its bearing within the pendent knob secures a close joint- 'ing and bearing between the two to the better exclusion of dirt, dust, and moisture to theV Watch-movement.
